  If your La Crosse Technology Weather Station isn't showing the outdoor temperature, try these steps: 1. Remove and reinsert batteries, starting with the remote temperature sensor, then the indoor weather station. 2. Move the remote temperature sensor closer to the indoor weather station. 3. Ensure all batteries are fresh. 4. Make sure there are no interfering electronic devices nearby, such as computer monitors, TVs, headphones, or speakers, as these can disrupt the signal.
